Be the first to identify what this is, and where it is located, and you could win a prize in the CNET Road Trip Picture of the Day challenge.

Update (Wednesday, 9:17 a.m.): The answer is a fermentation vat at the Maker's Mark distillery in Loretto, Kentucky.

Think you have a good eye for identifying mysterious photographs? If so, you could win a prize in the CNET Road Trip Picture of the day challenge.

Later this month, I'll be starting Road Trip 2010, my fifth-annual journey around a region of the United States in search of the most interesting places one can visit. In past years, I've traveled a total of more than 18,000 miles in the Pacific Northwest, the Southwest, the Southeast, and the Rocky Mountain/Continental Divide region. And this year, I'll be touring the Northeast and visiting military bases, factories, research institutions, waterfalls, architectural wonders, and much more.

But for now, I want to see how good you are at discerning meaning from sparse amounts of information. So, if you're the first person to e-mail me (at daniel--dot--terdiman--at--cnet--dot--com and using the phrase "Picture of the Day" in the subject line) with the correct identification of what is in this picture, and where it's located, you could win a prize.

One caveat: No individual can win more than two prizes. At the end of the trip, I'll be drawing a name from among all the daily challenge winners and giving out something a little more substantial to that person.

For now, then, good luck.

On June 24, Geek Gestalt will kick off Road Trip 2010. After driving more than 18,000 miles in the Rocky Mountains, the Pacific Northwest, the Southwest and the Southeast over the last four years, I'll be looking for the best in technology, science, military, nature, aviation and more throughout the American northeast. If you have a suggestion for someplace to visit, drop me a line. In the meantime, you can follow my preparations for the project on Twitter @GreeterDan and @RoadTrip.
